Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 23,461,435, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 23,461,435 | |
| -1 | -23,461,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,461,435.
Example:
1 x 23,461,435 = 23,461,435
and
-1 x -23,461,435 = 23,461,435
Notice both answers equal 23,461,435
With that explanation out of the way, let's continue. Next, we take the number 23,461,435 and divide it by 2:
23,461,435 ÷ 2 = 11,730,717.5
If the quotient is a whole number, then 2 and 11,730,717.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 23,461,435 | |
| -1 | -23,461,435 |
Now, we try dividing 23,461,435 by 3:
23,461,435 ÷ 3 = 7,820,478.3333
If the quotient is a whole number, then 3 and 7,820,478.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 23,461,435 | |
| -1 | -23,461,435 |
Let's try dividing by 4:
23,461,435 ÷ 4 = 5,865,358.75
If the quotient is a whole number, then 4 and 5,865,358.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 23,461,435 | |
| -1 | 23,461,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 239 | 677 | 1,195 | 3,385 | 6,931 | 19,633 | 34,655 | 98,165 | 161,803 | 809,015 | 4,692,287 | 23,461,435 |
| -1 | -5 | -29 | -145 | -239 | -677 | -1,195 | -3,385 | -6,931 | -19,633 | -34,655 | -98,165 | -161,803 | -809,015 | -4,692,287 | -23,461,435 |
